Very strange.....I can't get sks to work on my windows 7 lappy either.
Well iam on win8.1 but im glad that im not the only one having this problem.
I wrote a ticket today but havent recieved feedback on it yet.
To decribe my problem in detail ... i started up skinstudio and was promted with the first setup message, you know bla bla are you new to skinstudio or experienced...filled that out and had only the option close for it to confirm my selection.
When i pressed close Skinstudio turned off. When i started it up again it instantly closed and still does so without an error report.
DID bunch of things even cleaned the registry but no cure.
But i know someone will look into it
until then gaming time hehe
